The unit publishes a variety of supply-disposition data for the major grains in Canada, monthly in the Cereals and Oilseeds Review (STC 22-007) and annually in the Grain Trade of Canada (STC 22-201). This paper, an overview of the supply-disposition factors for the Canadian oilseed industry, is intended to assist in making more effective use of the two statistical publications noted above.
